On June 12, 2020, Chhanda, Sadia Afrin; Itsuno, Shinichi published an article.HPLC of Formula: 10472-24-9 The title of the article was Design and synthesis of cinchona-based chiral hyperbranched polymers and their application in asymmetric reactions. And the article contained the following:

Cinchona-based chiral hyperbranched polymers (HBPs) were designed and successfully synthesized via the Mizoroki-Heck (MH) coupling reaction. AB2 and A2B-type chiral monomers were prepared from cinchona squaramide derivatives, where A (vinyl) reacted only with B (iodophenyl) under MH reaction conditions. The chiral HBPs obtained by the MH polymerization contained cinchona squaramide moieties and demonstrated excellent diastereoselectivity and enantioselectivity in asym. Michael addition reactions of Me 2-oxocyclopentanecarboxylate and trans-β-nitrostyrene. These newly designed HBPs were structurally robust and could be reused for further reaction without losing their catalytic activity. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).HPLC of Formula: 10472-24-9
